Method _deps

packages/reflex-base/src/reflex_base/vars/base.py:2527–2576

Determine var dependencies of this ComputedVar. Save references to attributes accessed on "self" or other fetched states. Recursively called when the function makes a method call on "self" or define comprehensions or nested functions that may reference "self". Args
